The preparation method disclosed by the invention has the advantages of high ABS purity, few impurities and simple preparation process of the obtained ABS recycling material and excellent property and easiness for industrialization realization of reclaimed ABS.

Description

technical field [0001] The invention relates to the technical field of recycling ABS regenerated materials, in particular to a regenerated ABS flame-retardant modified material and a preparation method thereof. Background technique [0002] Today, China has entered the peak period of discarding household appliances, and more than 30 million discarded household appliances will be produced every year. Such a huge waste of household appliances will inevitably produce a large amount of waste plastics. There are three ways to recycle waste plastics: sanitary landfill, incineration for heat, and resource recycling. Among them, landfill and incineration are likely to cause waste of resources and secondary pollution, which is contrary to the theme of the era of green environmental protection. [0003] Nowadays, the recycling of waste plastics mainly adopts the method of recycling, mainly including direct regeneration, modified regeneration, gasification and oil treatment. However, ...
